Santa Anita officials said racing wouldn't stop, although the tote boards would be shut down, if the track faced a power outage. The wagering information, which is controlled by computers, wouldn't be lost. Furer said there are about 22 tote machines that could be up and running during a blackout. Escalators and elevators would be immediately turned off before the blackout to ensure no one gets hurt or trapped. The track is equipped with an emergency generator that would provide lighting.
